Security alarm turn on light and buzzer

As a school project I am making a home security alarm.
Im new to Node-red and dont understand everything yet.
I am using a PIR sensor and when it detects motion, the lights and buzzer should turn on.
However I want them to turn on for 5 minutes and I have to be able to turn them off earlier on my dashboard.

Can anyone help me with this?
Kind regards,

You can use the [delay] node to turn something off after a set time and it's fairly easy to do a dashboard with a button. What have you tried? Where are you stuck?

This sounds very similar to the question that was posed a few days ago by @ZenoVD - any relation to you??

I suggest you read that thread as it covers a number of the issues/questions/decisions you will need to consider/answer.

Better to carry on the original thread and ask specific questions about the points you did not understand. Otherwise you will just get the same answers again and still not understand.
